OIL-GIRCULATING SY$TE1VL Application filed July 23, 1925. Serial. No. .l5,659.

My said invention relates to lubricating systems for auton'iol'iiles oil the Ford or other type having a fly wheel and magnets associated therewith enclosed in a casing containing a well or sump oil? liquid lubricant in which'the said fly wheel partially suhmerged and from which sump said lubricant is thrown hy centrifugal force during); the rotation of said fly wheel.

The olojectof the invention is to provide simple and inexpensive means for forcing: the oil. to the front of the motor at all times durinp 'tl'ie operation ot the sznne'insurinn a nore C'iiiClQIll"(){Wl'fli'imi and venting; damage to the Marines :it lhe front end and at a distance from the well or" oil.

It is also an object oi: the ii'ivenl'ien to provide a device of this character which will continue to function when the oil hasp otlen low or below the normal oil level in the well in, the (rating. for the fly wheel or trans-- mission case.

Referring to the accon'ipanyinu drawings which are made a part hereoi and on which similar reference eharacterr'i indicate similar parts,

Figure 1 is a side elevation oi an automobile-of the type reterred to luau "rug; :1 portion oi. the crank ease broken away and illustrating the application ot' my invention.

Figure 5, a fragmentary detail. ill uistrnti the eflect upon oil. in the l'iottom of tee crank case or sump when a a low level.

In the drawings 1 have shown an en having a transmissirm case ll. a crank case 12 and a hreather pipe 13. A quantity of oil is contained in an oil, sump l t and in the which is disposed a. fly wheel i havii a T1119: gear 16 attached to one o tl ereol' and having ii-shaped magnets l7 supported in spaced relation From the opposite race thereof in the usual manner and when rotailing, constituting a series of "Fan. hladrs or tions by centrifugal force. ()il is thrown into the crank case where it luhricates the nected one end oi a gripe 19 disposed in an inclined pc'mition with ite lower opposite end- 'u'ovi led with an elbow E20 curving:

,errudually hetween its extremities and of an unohstructed internal construction. elhow 20 is tapped into the side of the hreuther pipe 13 in a. horizontal plane below the. plane the entrance end and terminates snhstantially flush with theintcrna surface '01? the some. i

Fly the ahove construction oil gaining admiseioitr thri'uieh the coupling 19 into the pipe 19 will flow by gravity through the breather pipe 13 into the front end of crank case 12 and finally hack into the sump 14: in the transmission case 11. In this manner the euegine is more thoroughly and effectively lubricated during the eontii'iuous entry of the oil into the emiplinn- 18. However, when the oil evel is low or below normal (see Fig. 5) it the entrance end of the coupling is dispoeed over the periphery of the revolving: magnets 17 they have the faulty feature of not delivcringoil. By experimenting I find that when the inlet end of the coupling is over the nimgnets they act a series of fans or tt'anhlades which according to the speed of the motor and depth of the oil form a concavity in the oil in the sump with the result that very little or no oil is centrifugally dieeliarn'ed "from the magnet ends hut the low oil level. in raised at the junction between. the fly wheel 15 and the ring gear 16. Also on account of the periphery of the ring gear hei'np; beyond the periphery of the fly wheel there is a blocking" action of the oil fanned hy the magnets, the ring gear teeth also as sistingr in blocking the oil by their fanning action shown in Fi In view oi the tore oing I provide the enlarged entrance end of the coupling 18 in thetransmission casing in line with the junchearings and 'p ravitatcs hack into the sump In the present invention in order to carry The , pass out without splattering or expelling the voil through the breather cap. Also the oil is cooled during its passage through the pipe 19 which keeps the oil nearer its normal body as shown by temperature readings under like conditions with and without tubes, e

If desired the pipe 19 may be tortuous to subject the oil to a greater cooling action.

Another very desirable feature of my invention is its unlikeliness to become clogged, which is almost impossible on account of the inverted position otthe entrance end of the coupling 18(any foreign matter being removed by the action of gravity or washed off by the splash of oil. 7

It will be obvious to those skilled in the art that various changes may be made in my device Without departing from the spirit of the invention and therefore I do not limit myself to what is shown in the drawings and described in the specification but only as indicated in the appended claims.

Having thus fully described my said in vention, what I claim as new and desire to secure by Letters Patent is:

1. The combination in an internal combustionen ine'havin a crank case with its iliOlWitlCl and rear portions sloping gently downwardly to form an oil sump and hav ing a fly wheel disposed between said sloping portions and a ring gear of slightly larger size than said fly wheel connected thereto, of an oil receiving nipple disposed in the fly wheel housing in the plane of the junction between the rear side of the fly wheel and the forward side of the ring gear and a pipe having one end connected to said nipple said pipe sloping slightly .;torward and downwardly and terminating in the breather pipe whereby when the oil in :the cranl: case is tanned by the magnets on the fly wheel said ring gear will obstruct or dam the oil and cause the same to be discharged through said pipe into the breather pipe, substantially as set forth.

2. The combination in an internal combustion engine, of an oil receiving 'n-ipple'disposed in the upper part of the fly wheel housing in inverted position (in line with the junction between the fly wheel and ring gear said nipple having a large unobstructed inlet end tern'iinating substantially flush with the inner surface of said housing in the path of the centri'lugally thrown oil and tapering gradually to its reduced outlet end, and a pipe having one .end connected to said reduced outlet end of the nipple and having its opposite end tern'lina-tingin the side of thebreather pipe, substantially asset forth.

In witness whereof, I have hereunto set my hand at Tampa, Florida this 2nd day of July, A. D. nineteen hundred and twenty five.
